Researchers at Japan's Kajimoto Laboratory at the University of Electro-Communications are developing a device that allows the user to engage in some telepresence smooching by furiously tonguing an apparatus that resembles an electric toothbrush or talk box. Sexy futurism?

Additionally, the kissing styles can be recorded for posterity. Your children's children will know that Keith Richards' mouth tastes like a bowling alley in Camden, New Jersey (but he'll still be around anyway). Says one researcher:

For example, if you have a popular entertainer use this device and record it, that could be hugely popular if you offer it to fans. The elements of a kiss include the sense of taste, the manner of breathing, and the moistness of the tongue. If we can recreate all of those I think it will be a really powerful device.
